CONCRETE TIE.

To all whom it may concern:

Be it known that I, CHARLES E. MARK- HAM, a citizen of the UnitedStates, residing at Williamsville, Wayne county, Missouri, have inventeda new and useful Concrete Tie, of which the following is aspecification.

This invention relates to improvements in railway ties, especially thattype made of concrete or plastic material.

Said invention has for its object, among other things, to provide forthe requisite yielding or cushioning of the tie under the action of thewheels of the car as in contacting with the rails carried by the tie.

A further object of the invention is to provide a sectional tie of thecharacter described adapted to have such yielding action or movement andyet possess the required strength and durability called for in a railwaytie.

A still further object is to provide for effectively holding the railsin position upon the tie as against possible casual displacement.

The invention consists of certain instrumentalities and featuressubstantially as hereinafter fully disclosed and defined by the claims.

This invention relates to ties made of concrete and other plasticmaterial, and its object is to provide an improved tie comprising aplurality of separate detachable sections secured together by metallicbinding devices.

In the accompanying drawing illustrating the preferred embodiment of myinvention, wherein it will be understood that various changes andmodifications of the details of the construction and arrangement of theparts may be made without departing from the spirit of my invention, Figure 1 is a plan view of my improved tie with the parts assembled andsecured together. Fig. 2 is a side elevation partly in section on theline 22 of Fig. l disclosing more particularly the rail-securingdevices. Fig. 3 is a sectional view on the line 33 of Fig. 1, showingmore especially the locking means for the tie-rods between the tiemembers. Fig. 4 is a sectional view on the line 44' of Fig. 1, showingone of the dovetailed recesses which receive the correspondingly shapedtie-rod terminals. Fig. 5 is a broken perspective view of one of thetie- Specification of Letters Patent.

rods, and Fig. 6 is a fragmentary sectional detailed view, showinganother form of the rail-securing devices.

In practicing my invention I employ a tie which comprises anintermediate member or section A, and du licate, interchangeable endmembers or sectlons B. The member or section A is provided with tongues1 re ceived by recesses or grooves A in the inner ends of the endsections B preferably as shown in Fig. 1, thereby preventing lateralmovement of any of the sections.

A groove 3 is formed in each side of the member A and continues upwardlyin the end sections to the upper edges thereof. A metallic tie-rod 4: isseated in each groove, the ends of said tie-rod extending over the topof the end sections and downwardly and let into recesses or sockets 6,said ends being enlarged or formed with Wedge shaped or dovetailedterminals 5 for anchoring the same in said recesses or sockets, thesections of the tie thus being firmly tied or connected together. Therecesses or sockets 6 are widened or enlarged toward the lateral edgesof the tie to initially receive the wedge shaped terminals 5. Afterinserting the wedge shaped portions of the tie-rod terminals into theenlargements of the sockets or recesses, the terminals are moved intothe correspondingly shaped portions of the sockets or recesses. Eachterminal 5 has a shoulder 7 at its upper end, and into each recess 6 isinserted an end-bifurcated looking device 8, one prong of which engagessaid shoulder as said device is forced to final position, securelylocking the parts together. By means of this arrangement the parts areelfectively held against possible separation while possessing therequisite resiliency.

In the end sections are formed other sockets or recesses 6 similar inshape to the recesses 6, and into these recesses are inserted the railsecuring clamps 9 which are flared downwardly and are received by saidrecesses 6 Said rail securing clamps engage over the base of the railsas shown, and in connection with these clamps are emploved similarend-bifurcated wedging devices 10 as those above described for holdingsaid clamps in effective engagement. In order, however, to provide forthe retention of the clamps against outward displacement, they are movedinto the narrow or lower wedgeshaped portions of the sockets 6 In theform of my invention as suggested by Fig. 6, it will be seen that inlieu of the bifurcated-ended resilient keys or members 8, I use simplyrectangular members, blocks or plugs 8 which are inserted into the sockets or recesses alongside of the rail-clamps, thus providing for equallyeffective in their final positions in engagement with the rail-bases.

\Vhat I claim is: v Y

1. A tie of concrete or plastic material, including a plurality ofmembers or sections, tie-rods for saidmembers or sections, andfastenings for said tie-rods comprising flared terminals upon saidtie-rods, and keys engaging said terminals, said terminals and keysbeing received by sockets in certain of said members or'sections ofcorresponding outline as said terminals.

2; A tie of concreteor plastic material, comprising a plurality ofmembers or sections, tie-rods for said members'or. sections andfastenings for said tieerods including flared terminals upon saidtie-rods, and keys adapted to engage said terminals, said terminalshavingat their upperends shoulders adapted to be engaged by said keys,said terminals and keys being received by sockets in said members. ofcorresponding outline as said flared terminals.

3. A railway tie of the character described, including a plurality ofmembers or sections, tie-rods for said members or seef tions andfastenings for said tie-rods, said securing the latter tie-rods being ofapproximately bail-like outline with their end portions at right anglesto the body or main portion, said body portion adapted to be appliedlaterallyto the intermediate section or member of the tie and the endmembers or sections of said tie, the end portions of said tie-rods beingadapted to'engage the upper surfaces of said end members or sections.

4. A concrete tie comprising a series of separate sections having atongue and groove connection and provided with grooves, certain of saidsections having sockets or recesses, removable metallic connectionsseated in said grooves and extending into certain of said sockets orrecesses, and devices locking said connections in said sockets,substantially as specified.

5. A concrete tie comprising a central section, two end sections havinga tongue and groove connection with said central section and providedwith sockets, t1e-rods for said sections, sald sections havmg recessesto receive said tie-rods, said end sections being provided withadditional sockets to receive Q theterminals of said tie-rods, andlocking devices holding said tie-rods in position.

In witness whereof, I have signed this specification in the presence oftwo subscribing witnesses.
